System Of Cars For Employees Design And Implementation Based On MVC Mode

This thesis firstly introduces different stages of a project, System of Cars for Employees (Yuangong Gou Che Xitong), and demonstrates main techniques in detail by cases in the project. From the perspective of supply analysis, the thesis introduces a easy-understanding instruction, bridging the project team and enterprise representatives. Due to the cooperation with each other, the project has successfully integrated existing models into a better work flow, which makes a good base for the future of the System. Secondly, the thesis introduces major techniques involved in this project by some cases, combined with related techniques, and illustrates the main idea of the project.This project is an interactive human-machine software, with a easy-changing feature. If customer's view and core function is combined tightly, it is very difficult to achieve such a flexible system. In order to deal with this problem, the project team has chosen model-view-control (MVC) design pattern.The software industry is increasing high demanding; customers usually ask for high-qualified software within a short time. As a response to that, designers usually modify previous successful models by adding new elements required in new software development. Such a manner is effective in time, human resources and material resources.The project in the thesis adopts a classical model is MVC, originated from Smalltalk. MVC can separate the logic of processing from visual interface. Such a configuration could make systematic function extension easier because even if one sub-system has been changed, there would no seriously harm to the others. According to such design idea, designers build up a MVC pattern to resolve the biggest problem.The new system has the following advantages, compared to the old one:1. Feasibility of modification. Customers require this System could set up and identify different categories of operators to guarantee the correctness of data.2. Statistical functions. The new system adds many statistical functions, according to customers' requirement. Such configuration can assists them to find out potential customers and thus make a higher profit.3. Stability. The new system is more stable than the old one.In addition, the system adopts some advanced techniques, such as Ajax, asynchronous technique which improve web page's interactivity, speed, and usability.The System is now in trial with all basic functions. Further steps will focus on web page design and the function of data mining.
